Astrocyte cells in the fruit fly brain are an on-off switch that controls when neurons can change and grow

Adaptable neurons are tied to learning and memory but also to neurological disorders. By studying fruit flies, researchers found a mechanism that controls neuroplasticity.
Currently, the only approved drugs for Alzheimer’s merely alleviate some of the symptoms — partially and temporarily — but do not stop the disease from progressing. (Shutterstock)

Why don’t we have a cure for Alzheimer’s disease?

It was first officially described 115 years ago, but we still do not have a cure for Alzheimer's disease. The human brain is extremely complex, and Alzheimer’s is its most complex disease.

Dementia patients are at greater risk for COVID-19, particularly African Americans and people with vascular dementia

Because dementia patients are more likely to acquire COVID-19, and because so many live in close-quarter facilities – like nursing homes – it's critical to vaccinate them as quickly as possible.

Air pollution may contribute to Alzheimer’s and dementia risk – here’s what we’re learning from brain scans

The tiny air pollutants known as PM2.5, emitted by vehicles, factories and power plants, aren’t just a hazard for lungs. A study finds more brain shrinkage in older women exposed to pollution.
More than half of patients with dementia also suffer from depression. If the depression remains untreated, the associated memory and cognitive problems worsen. Conversely, a significant history of depression seems to be a risk factor for dementia. (Pixabay)

Depression and dementia in the age of COVID-19: Two sides, one coin

Dementia and depression are two diagnoses that rob older adults of health and happiness. Despite their obvious differences, it is becoming ever more apparent that the two conditions are connected.

Does forgetting a name or word mean that I have dementia?

September is Alzheimer's Awareness Month and therefore a good time to talk about dementia. Alzheimer's is the most common dementia, but there are others to be aware of, a gerontologist explains.

The loneliness of social isolation can affect your brain and raise dementia risk in older adults

The social isolation older adults are experiencing as they try to stay safe from the coronavirus pandemic is raising new mental health risks, but people can take steps to protect themselves.

The importance of blood tests for Alzheimer’s: 2 neuroscientists explain the recent findings

A blood test to detect Alzheimer's disease in people who have symptoms and even those who don't has been shown to work. Scientists still need to improve its accuracy rate to almost 100%, however.
